Method for measuring the amount of coffee dispensed by a coffee grinder and device comprising such a grinder

摘要

The method involves measuring average speed of a grinding wheel on a number of turns or on time interval, where the time interval is in the order of 20 ms. The quantity/mass of coffee distributed on the number of turns or mass of coffee distributed on the time interval is deduced based on the speed from an experimentally obtained correlation table. The correlation table is stored in a memory. An independent claim is also included for an apparatus for preparing coffee.
